SPECIFIGATION forming part Of Letters ratent No. 694,516, dated March 4, 1902.

Application filed May 25, 1901.

To all whom, it may concern:

Be it known that we, MAURICE L. AKERS and WILLIS L. RICHARDS, citizens of the United States, residing at Ione, in the county of Morrow and State of Oregon, have invented a new and useful Panoramic Camera, of which the following isa specification.

This invention relates to cameras, and has for its object to provide an improved camera which is designed to take panoramic views from a fixed center and also arranged for taking fixed views as well, it being, furthermore, arranged to make complete circular exposures and also sectional exposures of'predetermined lengths.

Another object resides in the provision of improved means for rotating the camera and feeding the sensitive film in a predetermined relation, so as to secure an effective exposure of the entire length of the film during acomplete transit of thecamera and also to insure the accurate stopping of the camera and the camera and also at predetermined intervals in the transit to secure sectional views: Moreover, it is designed to arrange for conveniently starting the camera in its circular movement and also to provide for recharging the camera with a new film without the aid of a dark room.

With these and other objectsiu view the present invention consists in the combination and arrangement of parts, as will be'hereinafter more fully described, shown in the accom panyingdrawings,and particularly point-. ed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a rear elevation of the present form of camera with the back of. the camera-box removed. Fig. 2 is a vertical longitudinal sectional view of the camera from front to rear thereof. 3 is a top plan view with the top of the boxremoved. Fig. 4is a detail horizontal sectional Serial No. 61,899. (No model.)

looking at the inner ends of the adjustable stop-pins carried by the camera-box and for cooperation with the stopping andlocking rack. Fig. 7 is a detail perspective view of the camera looking at the front thereof. Fig.

8 is a detail view of one form of means for governing the rotation of the camera.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

In carrying out the present invention there other words, the upper chamber is designed for the mounting of the sensitive film and its cooperating elements, while the lower chamber is designed for containing the spring-actuated mechanism for rotating the camera,

feeding the film, and also for starting and stopping the movement of the camera.

For the support of the camera there is provided the usual tripod-head 3, upon the top of which is fixed a block 4, forming a base, from which rises a fixed shaft 5, that is held against rotation by means of a set-screw G, piercing the block and bearing against the side of the shaft. The .upper projected portion of this shaft passes through the bottom of the camera-box and has an upper terminal bearing in the partition 2, whereby the camera is adapted to rotate upon the shaft as an axis. In the front of the upper chamber there is provided the usual lens-tube 7, and at a suitable distance in rear of the tube there is pro- 0 vided a lower film-track 8 in the form of an angle-strip extending transversely across and secured to the upper side of the partition 2. A corresponding upper track 9 is secured to the under side of the top of the camera-box, 5

Ah the IQ? tical guide-rollers 10 and 11, which have terminal bearings in the top of the camera and the partition thereof. In front of the track and slightly beyond one end of the track, preferably the left-hand side of the camera looking toward the front thereof, as shown in Fig. 3 of the drawings and also in Fig. 1, there is mounted an upright shaft 12, having an upper terminal bearing in the top of the camera-box, which top is hinged to form a lid, so as to give access to the interior of the box at the top thereof. Upon this shaft there is placed a filled film-cartridge 13, which is designed to rotate loosely thereon, the free end of the film being passed between the adjacent guide-roller 10 and the upper and lower tracks and outwardly between the opposite guideroller and the opposite ends of the tracks, whereby the intermediate film portion 14 is passed transversely across the camera in rear of the lens. Slightly beyond the right-hand end of the track there is provided a feedroller 15, which is loosely mounted upon an upright shaft 16, terminally journaled in the camera top and the partition. It will be observed that the film passes across the front of this feed-roller,thence substantially half-way around the same, from which it extends inwardly and around the front of an empty film-carriage 17, which is fitted downwardly over the top of an upright rotatable shaft 18, journaled terminally in the top and bottom of the camera-box. Any suitable means may be provided for interlocking the shaft and the cartridge-as, for instance, a pin or lateral projection 19, carried by the shaft and snugly received within a corresponding notch or seat formed in the lower edge of the cartridge. The opposite cartridges are of the common or ordinary form, having the usual longitudinal slot for the connection of the respective ends of the film, whereby a rotation of the cartridge 17 is designed to feed the fil m from the other cartridge, as will be understood. It is designed to have the feed-roller 15 normally connected to its shaft, preferably by means of a ratchetdisk 20, fitted upon the upper polygonal end of the shaft and engaged by a spring-pressed ratchet-dog 21, these parts being arranged to interlock the shaft and disk for simultaneous movement or rotation in the direction indicated by the arrow to feed the film from the cartridge 13 to the other cartridge 17.

To apply motion to the receiving-cartridge 17, there is provided a suitable spring-motor 22, having the usual train of gears, which are in mesh with a pinion 23, provided upon the lower portion of the rotatable shaft 18. It will be noted that the motor is mounted upon the bottom of the camera-box and Within the lower compartment and has a winding-stem 24 projected through the bottom of the camera and constructed for the reception of a key whereby to wind the spring. When the spring-motor is in operation, the shaft 18 will also be operated, thereby turning the receiving-cartridge and feeding the film thereto.

It will be understood that the roller 15 has a frictionalsurface formed in any suitable manner to insure a rotation of said roller by the passage of the film in frictional contact therewith. To furthermore insure a proper engagement of the film with the roller, there is provided an elastically-yieldable pressureroller 25, as best indicated in Fig. 3, and lying against the front side of the roller 15, so as to press the film in firm contact therewith. This pressure-roller is journaled at opposite ends upon the respective terminals of the upper and lower angle pivotal brackets 26, which are respectively pivoted to the camera top and the partition in the manner shown in Fig. 3, wherein the upper bracket is pivoted at its middle or apex, as at 27, to the top of the camera, and an upright rod 28 connects the opposite free ends of the brackets, thereby completing a rocking frame which is elastically yieldable under the tension of a spring 29, having one end connected to the intermediate portion of the rod and its opposite free end in adjustable engagement with a rack 3 provided upon the inner face of the adjacent side of the camera-box, so as to vary the tension upon the frame and the pressure-roller. A suitable upstanding bowed guide 31 mm braces the outer side of the feed-roller.

For rotating the camera upon the shaft 5 the shaft 16 of the feed-roller 15 is projected into the lower compartment, as indicated in Figs. 1 and 2, and provided with a fixed pinion 32, which is in mesh with a circular toothed rack or wheel 33, carried by the fixed shaft 5, so that as the feed-roller rotates in the direction of the arrow in Fig. 3 the pinion 32 will travel about the fixed rack, thereby rotating the camera in the direction of the arrow placed at the outer side thereof in Fig. 3. It will be here observed that the camera is rotated in a fixed relation to the speed of the feed of the film, as it is the film that drives the feed-roller 15. Moreover, the periphery of the feed-roller should be of such a length as to cause a predetermined number of complete rotations of the feed-roller in passing around the circular rack or track. The proper length of film to take in a con1- plete transit of the lens may be readily determined by computing the length of the circumference of a circle having for its axis the focal length of the lens, which in the present camera is the length between the inner side of the lens and the focal plane or the position of the film, as it is at this point that the lens focuses. In practice a suitable length of some black flexible material is connected to each end of the film, so that the latter may be entirely wound upon the receiving-cartridge, so that the entire film may be contained upon either cartridge, whereby the film is not exposed in placing the same within the camera and also when removing the film, and thus the camera may be recharged without requiring a dark room. Furthermore, the peripheral length of the feed-roller is a fractional to the total number of rotations of the roller lens, the inner end of the latch-being pro in making a complete transit about the axis of the camera, whereby the film will be completely'unrolled from one cartridge and rolled upon the other by a complete transit of the camera.

For starting, stopping, and locking the camera there is provided a latch-arm 34,which projects in opposite directions through avertical slot or opening 35, formed in the front of the camera-box and alined directly below the jected into the lower chamber or compartment andadjacent to the under side of the circular track 33. The inner end of the latch is pivoted in a bifurcated bracket 36, carried 'by the camera-box, so that the outer free end of the latch may be moved vertically and normally'lie at the bottom of the slot. Fixed upon the central shaft 5 is a circular disk 37, provided with an upstanding marginal rim or flange 38, upon which the intermediate portion of the latch rests. In the upper edge of this rim there is provided a plurality of vertical notches or seats 39, 40,

41, and 42, which are arranged at equal intervalsof ninety degrees, it of course being understood that a greater number of notches may be employed, if desired. The latch'normally occupies the notch 39, whereby the camera is locked against movement by the spring-motor, and by raising the latch out of engagement with the rack formed by the notched rim the camera-box is free to be M tated by the spring-motor, the latch being carried with the box and traveling upon the rim or rack until it drops into the'next adjacentnotch 40, thereby stopping and locking the camera at the completion of a quarterrevolution.

To prevent the camera-box from rotating too far for the latch to engage with the first notch, there is 'providedan adjustable stop device, consisting of a rectangular frame 43, set into an opening in the front of the camera-box and at the right-hand side of the latch when'looking at the front of the camera. 'Slidably mounted through corresponding perforations in the inner and outer side of the frame are a plurality of stop-pins as, for instance, three pins 44, 45, and 46'the opposite ends of which project beyond the frame and are provided at their outer ends with suitable enlarged heads or finger-pieces for convenience in adjusting the same and to a slot or notch 50, formed in the outer end of the frame and intersecting the opening through which the pin slides. The pin is also capable of rotation, so that by drawing the pin outwardly until the projectionpasses through the notch and then turning the pin slightly the projection may be engaged with the outer side of the frame, as indicated by the pins 45 and 46, thereby to hold .the pins withdrawn from the circular rack and out of position to cooperate therewith. At an interval of ninety degrees from the first pin 44 there is provided an external stud or projection 51 upon the outer margin of the circular rack 37 and located in the path of the said pin, whereby when the camera has rotated to bring the pin into engagement with the stop shoulder orprojection 51 the camera will be stopped and the latch will drop into the adjacent notch 40, and thereby lock the camera against accidental rotation in opposite dire'ctions. As indicated in Fig. 6, the stoppins are arranged in different horizontal planes and the circular rack is provided with other stop projections 52 and 53, located in are drawn outwardly and the intermediate pin 45 is set to bring its inner end adjacent to the circular rack, whereby upon the rotation of the camera the pin will strikethe'pro} j ec'tion 52, whereupon the latch will drop into the adjacent notch 41, thereby locking the camera after the completion of a semirotation. It will be understood that the impetus of the camera is suflicient to carry the latch over the notch '40 Without dropping therein,

, the latch engaging with the notches only when stopped opposite one of the same by means of one of the adjusta-blestop-pins. It will be observed that the stop projections are arranged at predetermined intervals about the circular rack with" respect tothe respective pins and the notches are disposed beyond the respective projections according to the interval between the corresponding pin and the latch, so that the pins and projections and the latch and the notches may simultaneously cooperate, for the relation of the pins and the latch remain unchanged. For making a complete rotation or transit of the camera all of the pins are withdrawn, so that'the latch may travel entirely around the circular rack, there being a ratchet-notch54'formed just in advance of the initial notch 39 or between the latter and the first projection 51 and arranged so that the latch will au'tomat ically drop into said ratchet-notch and stop the camera after it has made alittle more. than a complete rotation. The cameramay be given more than one complete rotation,.as the film is lengthened by the application of flexible strips to the opposite ends thereof It is of course desirable that the adjustable stop-pins should set nearly radial with respect to the circular rack, and therefore the front of the camera-box has been made polygona'l and the pins set in that portion of the front which gives the desired disposition of the pins.

\Vhile the outer free end of the latch has been arranged for convenience in lifting the latch out of engagement with the circular locking-rack, it is also designed to have the latch and the shutter simultaneously operated by means of an ordinary air-bulb, and in carrying out this feature there is provided a pair of telescoped cylindrical air-chambers 55 and 56, similar to those commonly employed in connection with camera-shutters and mounted vertically within the lower compartment and directly below the latch, the inner and movable cylinder or tube having a pivotal connection 57 with the latch, so that the elevation of the tube 55 will also raise the latch out of engagement with the rack. Extending through the bottom of the camera-box is a three-way coupling or T 58, one branch of which passes upwardly through the camera-bottom and communicates with the air-cylinders, the lateral branch, which lies below the camera-bottom, being connected to a tube 59, that communicates with the shutter mechanism in the ordinary manner, and the pendent branch is provided with a flexible tube 60, having an outer terminal air-bulb 61, so that by compressing the bulb the shutter and the latch will be simultaneously operated to uncover the lens and release the camera-box for rotation by the spring-motor. When the camerabox has been brought to rest by the stop mechanism, the air-bulb is released, thereby simultaneously closing the shutter and permitting the latch to drop into engagement with the locking-rack.

As best indicated in Fig. 3 of the drawings, it will be seen that light-excluding vertical partitions 62 are provided at opposite ends of the film-track and extend from the track to the front of the camera and at opposite sides of the lens, the partitions also extending from the horizontal partition 2 to the top of the camera, thereby excluding light from entering the front portion of the camera and attacking the sensitive film.

It will of course be apparent that when the camera is moving it is essential that only a comparatively narrow portion of the film be exposed to the light entering through the lens,

. and therefore there has been provided a pair of opposite adjustable reducing-partitions 63,

each of which has one vertical end hinged to the top and bottom of the upper compartment, as at 64, and capable of being swung horizontally in a direction front and rear of the camera. The rear swing of each adjustable partition is limited by means of a stop-strip 65, secured to the upper side of the bottom of the upper compartment and inclined from the hinge of the partition rearwardly and inwardly toward the film-track, so that when the partition is engagement with the stop, as shown in full lines in Fig. 3, the outer free vertical edge of the partition is in engagement with the front side of the film, and the partitions are converged, so that a comparatively narrow exposure-opening is provided between the outer free edges of the reducing-partitions. The stiff free ends of the partition do not lie in direct contact with the film, but are provided with longitudinal flexible strips 66, which engage the film, so as to exclude light and prevent injury to the film. In making a time exposure when the camera is at rest the partitions are turned or adjusted to the positions indicated in dotted lines, whereby the entire portion of the film which is in the filmtrack is exposed. For convenience in adjusting each hinged partition it is mounted upon a rotatable spindle, the upper end of which is projected through an opening, in the top of the camera, as at 67, (shown in Fig. 1,) and formed into key stems or shafts for the reception of a key to rotate the shafts, or the same may be formed into finger-pieces, as desired.

In order that the camera-box may be prevented from rotating too rapidly, there is provided governing means, consisting of a rotary fan mechanism 68 (indicated in Fig. 1) and mounted upon the bottom of the camera within the lower compartment. This fan has a train of gears 69, which are in operative relation with respect to a fixed wheel or toothed track 70 upon the fixed shaft 5, whereby the fan is driven by the rotation of the camera and the resistance of the fan is utilized to re tard the movement of the camera and produce a steady and uniform rate of movement. Another governing device has been shown in Fig. 8 and consists of a gear 71, mounted upon the center of the bottom of the camera-box and loosely receiving the shaft 5. This gear is in mesh with another gear 72 of the same diameter and carried by the upper end of a rotatable vertical shaft 73, piercing the head of the tripod and the block thereon, the lower end of the shaft being provided with a crank-handle 7-t for manipulation by the operator of the camera to prevent too rapid rotation of the camera-box.

As indicated in Fig. 7 of the drawing, the hinged top of the camera-box is provided with an opening 75 for the exposure of the ratchet device upon the top of the roller 15, and thereby to permit of the disengagement of the pawl from the ratchet-disk, should it be desired to rotate the feed-roller independently of the rotation of the camera. This opening is normally closed by means of a metallic cover 76, hinged to the outer side of the top of the camera-box and provided at its opposite end with a bifurcated extension 77 for engagement by a turn button 78, mounted upon said top and designed to hold the cover closed. In the center of the cover there is provided a perforation 79, designed IIC - to receive the top of the. rotatable shaft 16,

, stop devices.

so as to provide anupper terminal bearing therefor.

It will be understood that the top of the camera-box is open to permit of the film being mounted in place, after which a light-excluding plate 80- (best shown in Fig. 2) is dropped downwardly, so as to rest against the back of the upstanding flange portion of the lower film-track, and then the top is closed downwardly, so that the .upper track may engage the top of the said plate, and thereby hold the same in place to exclude light from the film.
